Description
Technical field
The invention belongs to metallurgical slag Treatment and recovery and utilize technical field, specifically refer to a kind of method of utilizing slag washing ball milling mud production geology polymkeric substance.
Background technology
Slag washing ball milling mud be particle diameter be less than 30mm magnetic slag by adding the tailings after Water type ball milling magnetic separation particles steel, a kind of mud that last tailings liquid obtains through settling tank classification natural sedimentation after the magnetic separation of secondary wet magnetic separation device again, its essence is still a kind of steel slag tailings, is commonly called as tail mud in production scene.By slag washing ball milling mud sampling analysis is found, compare with the steel slag tailings of not washing ball milling, both chemical compositions are very nearly the same, wherein, and the P of slag washing ball milling mud
2o
5decrease with iron level, CaO, SiO
2, Al
2o
3, SO
3increase to some extent with basicity.But due to long-time immersion, slag washing ball milling mud active substance all reacts completely with water substantially.Slag washing ball milling mud fineness is little, easily infiltration, and saturated aqueous rate is about 20%, is difficult to dehydration, easily harden again after dry, thereby cause being difficult to transportation and stack, severe contamination production scene.This mud is phosphorous simultaneously, sulphur is very high, is not suitable for being directly used in cement and other building materials.
Geopolymer (Geopolymer) is to study in the world in recent years one of very active non-metallic material.The concept of geopolymer (Geopolymer) is first proposed by J.Davidovits in eighties of last century the end of the seventies.This material be that new development is in recent years got up, likely in many occasions, replace cement, and have than the cement type material of Good All-around Property more.It is to take clay, industrial residue or slag as main raw material, through suitable art breading, and the class Novel Inorganic Polymers material obtaining by chemical reaction under lower temperature conditions.Geopolymer is considered to by geochemistry process (Geochemistry) or manually imitates geology Synthesis (Geosynthesis) produce, take inorganic polymer as matrix, hard artificial rock.It has that intensity is high, sclerosis is fast, acid-alkali-corrosive-resisting etc. is better than the special performance of ordinary Portland cement, has the advantages such as material is abundant, technique is simple, cheap, save energy simultaneously and caused domestic and international material expert's very big interest.
The basicity of slag washing ball milling mud is between 2.9～3.3, and higher level in belonging to, has higher lateral reactivity, and its radioactivity is lower, far below relevant national standard.These good fundamental propertys provide possibility for slag washing ball milling mud is used for geopolymer.Slag is washed to ball milling mud by manufacturing geopolymer, the comprehensive utilization added value of slag washing ball milling mud will have been improved well, solve a difficult problem for the current contaminate environment of slag washing ball milling mud, what is more important, with slag rinsing ball, grind in the standby technique of geology polymer material without " the two mill one burnings " calcining process that uses as produce a large amount of consumption of natural resource and the energy silicate cement, and Carbon emission is few, the carbonic acid gas discharging in geopolymer production process is according to the study only 1/5th of silicate cement.Therefore, how to maintain the activity of steel slag ball-milling mud itself, and as the stability after building materials, and recycling slag washing ball milling mud is a urgent and important job.
Summary of the invention
Object of the present invention is just to provide a kind of method of utilizing slag washing ball milling mud production geology polymkeric substance, the method can be washed slag ball milling mud effectively as geology polymer material, and can solve the problem of environmental pollution that mud that slag washing produces causes, realize resource secondary and effectively utilize.
For addressing the above problem, the method for utilizing slag washing ball milling mud production geology polymkeric substance of the present invention, comprises the following steps successively:
1), will slag carry out solid-liquid separation after washing, and to control the moisture weight percent of solid be 5～10%, obtains the dry base of dirt mud;
2) in the dry base of dirt mud, add concrete retarder and mineralizer, mix, wherein, the weight of described concrete retarder is 0.1～0.5% of described dirt mud dried basis weight amount, and the weight of described mineralizer is 3.5～10.5% of described dirt mud dried basis weight amount;
3) the dry base of dirt mud is further dry, making its water content is 0.1～1.0%, obtains the thick product of geopolymer;
4) by the thick product grinding of geopolymer to granularity, be 310～560m
2/ kg, obtains geopolymer product.
Further, described concrete retarder is one or several in phosphogypsum, citric acid gypsum, desulfurated plaster, fluorgypsum.
Further, described mineralizer is one or more and the alkaline matter mineralising mixture that calcining 25～95min forms naturally at 850～1100 ℃ in kaolin, wilkinite, sepiolite, wherein, the weight ratio of the one or more combination thing in kaolin, wilkinite, sepiolite and alkaline matter is 0.2～4.5:1.
Also further, described alkaline matter is one or several in sodium hydroxide, potassium hydroxide, salt of wormwood, sodium bicarbonate, sodium carbonate, saleratus.
It is main raw material that the method for utilizing slag washing ball milling mud production address polymkeric substance of the present invention be take slag washing ball milling mud, through pre-treatment, add additive, dry control water, the steps such as grinding, obtained intensity suitable with commercially available cement, the geopolymer that high comprehensive performance has wide range of applications, thereby solved former slag washing ball milling mud non-activity in building materials, the bad phenomenon such as expand, the comprehensive utilization of washing ball milling mud for slag provides a new approach, can reduce slag washing ball milling mud and abandon the pollution to environment, real realization " turning waste into wealth ", be conducive to environmental improvement and environment protection.Wherein, in the dry base of dirt mud, add concrete retarder can effectively keep the hydration characteristics of slag, keep having water activity, make not aquation, the not gelling of slag dirt mud, after later stage and hydrate, can possess some strength, if do not keep active, slag does not just have intensity as geopolymer.Adding of mineralizer is equivalent to add grog in cement, increases the gelling property of ground polymers.
Simultaneously, geopolymer of the present invention can replace Portland cement and non-metallic fillers, be widely used in the fields such as automobile and aircraft industry, non-iron casting and metallurgy, civil engineering work, traffic and salvaging, plastics industry, nuclear leakage and heavy metal contamination are speedily carried out rescue work, Mine filling, can the obsolete comprehensive utilization of shape, improve to greatest extent the added value of utilizing of solid waste.
